/* ============================================================
   Course page: the request form - Register interest and Join the waiting
   list (template-parts/offering/request.php; stage 4, not designed: the
   working pattern from the theme's tokens and buttons).

   - The dialog (with JS): full screen on phones; from 600px a centred
     card up to --request-panel-width wide with a navy backdrop, its body
     scrolling inside. Opens and closes like the listing's filter panel
     (a short fade and rise, no rise under reduced motion).
   - Inline (without JS, ?request=...#request): a Cream section after
     Dates & Prices holding the same panel as a White card.
   - Fields: Poppins 16 (no zoom on iOS), Grey Dark outlines (3:1 for
     controls), the error red for invalid fields, the alert and the lines.
